STARCH-TABLE.

SPECIFICATION forming part of Letters Patent No. 275,318, dated April 3, 1883.

Application filed May 29, 1882. (No model.)

T 0 all whom tt may concern:

Be it known that I, WILLIAM ALLEN, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented new and useful Improvements in Starch-Tables, of which the following is a specification.

My invention relates to tables employed in the manufacture of starch, glucose, or grapesugar to separate the gluten or other substances from the starch. In this process tables of great length are usuallyemployed, and they are required to stand at a substantially uniform slight inclination throughout their entire length to permit a uniform flow of the liquid lengthwise of the tables. In use it is found that from various causes the position of these tables changes,varyingtheirinclination,whieh interferes materially with the separation, and is usually a source of waste. v

The object of my invention is to provide an tfficient means for the ready adjustment of these tables, and for this purpose I have designed and constructed the appliances repre-' sented in the accompanying drawings, in which I Figure 1 is a lengthwise central vertical section of a portion of a starch-table supported on suitable framework, representing my improvements in place. Fig. 2 is a transverse vertical section on dotted line a; on Fig. 1. Fig. 3 is an isometrical representation of my improvements in place. 1

1n the figures, Arepresents a floor of a suitable building, supported upon flooring-timbers B, having proper supports 0.

At D are represented postsv rising from the floor at proper intervals and to a suitable height. These posts D support transverse biaams E, employed to support the starch-tab es.

At a and b are represented metallic-like portions produced in incline or wedge form, which, when their inclined face edges are placed in contact, will have their outer upper and lower edge faces substantially parallel. These parts in this instance are produced in hollow or trough form, having their contiguous edges produced in sawtooth-ratchet form to engage each other in such a manner as to prevent the parts slipping on each other.

At 0 is represented an outward-projecting rib of bar form, extending transversely across the outer face of the wedge portion a. These wedge portions to are placed upon the transverse beams E, which support the tables, and in such position thereon as to be under the sills F or side beams of the tables. In this position these wedge portions are fixed to the beams by means of the transverse rib or bar 0, which is gained into the upper face of the beams centrally. The upper wedge portion, b, is placed in position on the under wedge portion, a, in such a manner that their saw-toothed corrugations will engage each other.

At H is represented a metallic shoe placed in position on the upper wedge portion, b, having its under face grooved lengthwise to receive the upper edge of the wedge in such a manner as to slide therein lengthwise freely.

The upper face of the shoe is also grooved lengthwise to receive the under edge of the sills or side beams, F, of the tables. The side beams or sills, F, are placed upon the shoes H, having their under edges supported in their grooved upper edges. These sills are suitably separated, and are connected at proper intervals by means of transverse bars I, having their ends gained into their upper edges and securely fixed thereto.

At K are represented the vertical side and at L the vertical end portions of the table, of wood, of proper dimensions, having their ends securely fixed to each other in rectangular form.

At 01 is represented the floor or wood bottom of the table, consisting of suitable plank having their edges grooved and tongued to engage each other. These planks are securely fixed to the under edges of the sides K and ends L,-producing a table of pan form. The inner surfaces of these pan-formed tables are provided with a metallic lining ofzinc or other suitable material, as represented at e, to prevent leakage. These tables are supported in proper position on the lengthwise side sills or beams, F.

The metallic shoesH are provided centrally with a lateral projection, h, to receive the end portions of a lever employed to lift the table.

At N is represented a lifting-lever of suita- IDU' ble construction or of convenient form for the purpose of lifting the tables. This lever has its fulcrum-support in a suitable chair (represented at 1?) consisting of a foot-plate, from which rise standards i, between which the lever H is supported upon a fulcrum-pin, it, passed transversely through the parts in such a manner as to permit the lever to oscillate thereon. These standards are provided with a suitable number of holes above each other, into which the fulcrum-pin may be changed to fit it in the best manner for the purpose. In use the foot-support of this lever is designed to rest on the transverse beams under the tables in such relative position thereto that the curved toe of the lever shall engage the lateral projection It upon the sides of the shoe in such a manner that the operator by means of the free arm of the lever may be able to raise the table to adjust the upper serrated or saw-toothed wedge to hold the table at a higher or lower level for the purpose of properly leveling the table. It will be seen that this lever is connected with its foot-support in such a manner as to be removable with the lever from place to place, when required, for the purpose'ot' leveling the tables. 1

i From the foregoing'it will be seen that in the use of my improvement the lilting-lever and its fulcrum-support, pivoted thereto, can be readily removed from one support of the table to another, or to any other point of support, and can be employed to lift the table to permit the upper wedge saw-toothed portion to be moved endwise in either direction to hold the table at a higher or lower level to any degree within the limits of the device.

By this construction and arrangement of the parts I produce a cheap and efiicient device by which the tables may be readily adjusted with all the accuracy necessary for the purpose, and the means employed are of a spending inclines or wedges supported by the v floor-beams; and I am'also aware that it is not new to adjust the wedge so as to level the starch-table, and therefore these features are not broadly claimed by me; but

What I claim as my invention is- 1. The combination, with the table and with its supports, of an adjusting mechanism consisting of subtantially like inclined or wedgeformed parts having their contiguous inclined edges corrugated transversely, substantially as and for the purpose hereinbefore set forth.

2. The combination, with the movable wedgelike portions 1) and with the table, of a shoe or grooved bar, H, to receive the upper edge of the wedge-like portion and the under portion of the table-beams, substantially as and for the purpose hereinbefore set forth.

3. The combination, with the serrated wedgelike portions and with the shoe supporting the table on the serrated wedges, of a lever capable of use in connection with the shoe, substantially as and for the purpose hereinbefore set forth.

WILLIAM ALLEN.
